(The heroine's luck is SSS+, and she cannot type "+" due to system reasons)
(It is not yet confirmed whether there will be a male protagonist.)
On the day when the end comes, space will turn upside down. When humans woke up, they found that the mountains and rivers were still there, the birds and beasts were extinct, and all humans were marked with a "luck value" scale.
Some people burned their luck and died suddenly because they won a bottle of water, and some people were wiped out by the system because they were rated F. Only Cheng Yi, with the golden "SSS+" koi on his head, is still alive.
When all living beings knelt down to open the treasure chest that had exhausted their luck and thanked the gods for an epic weapon - Cheng Yi tore up the rules and dyed the white box into gilded gold.
What fell out of the golden light was a divine-level weapon that made even Chief System Larry's pupils tremble - a black pocket watch entwined in star trails, with words from before the birth of the universe engraved on the dial.
*************
When others were struggling to scrape the beast's health bar, Cheng Yi struck, and the beast's blood bar was empty; when others were afraid of death and dared not challenge the world's beast king, Cheng Yi struck, and the beast king's blood bar was empty.
While others were shrinking back and living a hard life, Cheng Yi, her sisters and brothers reached the pinnacle of life and lived a happy life together.

Unconventional apocalyptic writing.
